IMPROVEMENT IN SEWING-MACHINE TABLES.

Specification forming part of Letters Patent No. 170,4 16, datedNovember 23, 1875; application filed March 6, 187-5.

To all whom it may concern:

Be it known that I, HARRIET RUTH TRACY,

- of the city, county, and State of New York,

have made certain new and useful Improvements in Frames forSewing-Machines; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this description, and in whichFigure 1 represents an end "iew of so much of a sewing-machine frame asis necessary to illustrate my present improvements. Fig. 2 represents atop or plan view of the parts shown in Fig. 1, and Fig. 3 represents anedge view of the parts shown in Fig. 1 when turned down.

My present improvements have reference, first, to an improvement insewing-machine frames. whereby the sewing-machineattachment for whichLetters Patent were granted me April 7, 187 4, can be applied tosewing-machines in a more economical, expeditious, and secure mannerthan they can as sewing-machine frames have heretofore been constructed.

In the drawings, the part marked A represents the outer metallic part ofone of the end frame-pieces of a sewing-machine frame. The middle partmay be filled in with any suitable ornamental frame-work. One suchdesign or frame-work is shown in the drawings. B B represent ears, whichare cast with the part A, and project out, as indicated in the drawings.To these earpieces my said patented attachment can be convenientlyhinged, saving a great deal of expense to the manufacturer or person whoapplies the attachment to the sewing-machine frame, although saidearpieces B form no part of my patented attachment, to which referencehas been made but, as before stated, they are an improvement upon thesewing-machine proper, whereby said attachment can be applied withgreater facility to sewing-machine frames, and that, too, without theuse of independent and separate clamping-pieces. Lugs or ears C 0v arecast with the end frame-pieces A, to receive small rolls or wheels D,which are pivot-ed or-journaled to turn between said ear-pieces, one ofsaid rolls or wheels D being arranged at each lower corner of thesewing-machine frame, and arranged so as to turn in planes parallel withthe sides of the sewing-machine frame, and at right angles to the 'endpieces A. By this arrangement the motion of the operator in working thetreadle, and in working at the table of the machine, is not calculatedto cause the machine to move or roll off, as would be the case if thesaid rolls were arranged to turn in planes parallel with the end piecesA of the frame. I contemplate, however, combining with said rolls orwheels clamping-wedges, or other fastening, if found necessary ordesirable, whereby the operator can quickly clamp said rolls rigidly inposition, and release them again as oocasion may require.

By means of my improved end frame all sewing-machines may be soconstructed as to receive my patented improvement referred to withoutalteration, expense, orinjury.

I claim as my invention and desire to secure by Letters Patent- An endframe for a sewing-machine, consisting of the supporting-frame A,provided with ears B, lugs O, and rolls D, all constructed and arrangedas shown and described, for the purpose specified.
